ABSTRACT
Herein we report the fabrication of an advanced sensor for the detection of hydrogen sulfide (H2 S) at room temperature, using thin films of rare-earth metal (RE)-based metal-organic framework (MOF) with underlying fcu topology. This unique MOF-based sensor is made via the inâ
situ growth of fumarate-based fcu-MOF (fum-fcu-MOF) thin film on a capacitive interdigitated electrode. The sensor showed a remarkable detection sensitivity for H2 S at concentrations down to 100â
ppb, with the lower detection limit around 5â
ppb. The fum-fcu-MOF sensor exhibits a highly desirable detection selectivity towards H2 S vs. CH4 , NO2 , H2 , and C7 H8 as well as an outstanding H2 S sensing stability as compared to other reported MOFs.
